Specification

Overview

Input and Output

Input: Detects vibrations in its environment.
Output: Provides a digital signal (High when no vibration, Low when vibration is detected).

Physical Characteristics

Dimensions: Small and compact, typically around 3.5 cm x 1.5 cm.
Material: Plastic housing with metallic contacts.
Weight: Very light, making it easy to integrate into various projects.

Technical Specifications

Vibration Detection: The sensor responds to vibrations by changing its output state.
Output State: Normally High, goes Low when vibration is detected.

Additional Features

Sensitivity Adjustment: Some versions may allow adjusting the sensitivity to better suit different applications.
Mounting Holes: Often includes holes for easy mounting in projects.

How to Use

Connect the Sensor: Wire the VCC pin to the power source, GND to the ground, and the OUT pin to a digital input pin on the microcontroller.
Power On: Ensure the module is powered correctly.
Read the Output: Monitor the digital output pin from the sensor. When the sensor detects vibration, the output will go Low.
Adjust Sensitivity: If your module allows, adjust the sensitivity to detect different levels of vibration.

The SW-420 NC Type Vibration Sensor is ideal for applications where vibration detection is needed, such as security alarms or interactive projects. Its simplicity and ease of use make it a popular choice among hobbyists and engineers.
